ubuntu出现The System is running in low graphics mode问题解决

当ubuntu出现“The System is running in low graphics mode

Your Screen, graphics card,and input device settings could not be detected correctly. You will need to configure this yourself.”

 解决方法1：

cd /etc/X11
sudo cp xorg.conf.failsafe xorg.conf

 解决方法2：

sudo apt-get install nvidia-current

sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install gdm
reboot

再一次ctrl+alt+F1输入用户名和密码进入文字界面

sudo service lightdm stop
sudo dpkg-reconfigure gdm3
sudo reboot

目前只尝试用了方法1进行了测试，已经跑了24小时还没出现问题，后期试过之后再回来反馈。
